Title: installing fan switch on dash
Post by meatman on May 1^st, 2008, 9:56pm

hi
i am still having problems with my wiring loom until i can source a good replacement would it be possible to install a switch on the dash so i can manually switch on the fans.
if it is possible how would i go about it has anyone done this before would it just be a case of taking the feed for the switch from the green fan relay
cheers
mark

meatman.
The only time you really need the fans is when using the aircon,even in a moderate traffic jam they dont cut in.It would be a fairly simple operation to go direct to the fans without the relay via a switch,but is it worth the trouble?The wiring loom can be rebound if you are not given to fits of rage!as it is somewhat time consuming.

If your fan circuit is working fine but it's just the ECU or thermoswitch that aren't working then a simple switch can be fitted to trigger the fans. However if you're contemplating fitting a switch because one or more of the fans aren't running, or you know there's a problem in the circuit, then I would advise against it.

The fan circuit on the Scorpio is relatively complex (well, for a fan circuit at least!) and the green relay is actually three relays in one to provide the two speeds of operation.

When I had problems with my fan circuit, I traced it to a burn out loom (all the insulation had charred and was falling off) behind the front crossmember. I cut out the damaged section and replaced it with new wires and it then worked fine on both speeds with no further attention.
